What is the density trend in halogens as you go sown the group?
As you move down the group of halogens in the periodic table, the density generally increases. This trend is due to the larger atomic and molecular masses of the heavier halogens, which outweigh the increase in volume. For example, fluorine and chlorine are gases at room temperature, while bromine is a liquid and iodine is a solid, reflecting their increasing densities. Thus, the trend shows that as you descend the group, the halogens become denser.
Does group 7 have a high or low density?
Group 7 of the periodic table consists of the halogens, which generally exhibit low to moderate densities. As you move down the group from fluorine to iodine, the density increases, with elements like bromine and iodine having higher densities compared to lighter halogens like fluorine and chlorine. However, overall, halogens are not known for high densities compared to metals or heavier elements.
What happens to the reactivity of halogens as you go down the group?
the reactivity of halogens goes on decreasing as we go down the group, because of increasing in atomic size of the respective element.
Does halogens reactivity decreese as you mov down the group?
Nope.
What general observations can be made of trends within rows and groups for density?
Within a row, as you move from left to right, the trend is typically an increase in density due to the increase in atomic number. Within a group, as you move down, the trend is typically an increase in density due to the increase in atomic mass and the addition of more electron shells.

What is the trend in melting points as you go down the group of halogens?
The trend in melting points as you go down the group of halogens is that they generally increase. This is due to the increasing number of electrons and atomic size which results in stronger van der Waals forces between the atoms, leading to higher melting points.
What is the density of the element chlorine?
The density of chlorine is 0.00321g/cm3. The density of the halogens or group 17 elements increases down the group, which is why bromine is liquid and astatine is a solid at room temperature.
What happens to the reactivity of halogens as you go down the group?
the reactivity of halogens goes on decreasing as we go down the group, because of increasing in atomic size of the respective element.
Does halogens reactivity decreese as you mov down the group?
Nope.
What is the trend of effective nuclear charge down a group in the periodic table?
The trend of effective nuclear charge down a group in the periodic table generally decreases.
What is the trend in melting point and boiling points of the elemets in group 1 and 7?
In Group 1 (alkali metals), the melting and boiling points decrease as you move down the group due to the increase in atomic size and metallic bonding. In Group 7 (halogens), the melting and boiling points increase as you move down the group due to the increase in atomic size and London dispersion forces.
What general observations can be made of trends within rows and groups for density?
Within a row, as you move from left to right, the trend is typically an increase in density due to the increase in atomic number. Within a group, as you move down, the trend is typically an increase in density due to the increase in atomic mass and the addition of more electron shells.
What do you predict the trend in atomic mass will be going down a group?
The atomic mass increases down a group.
How does the reactivity of halogens change as you go down group 7?
As you go down group 7 (halogens), reactivity decreases. This is because as you move down the group, the outer electron shells of the halogens are further away from the nucleus, making it harder for them to gain an electron and react with other elements. Additionally, the atomic size increases which leads to weaker intermolecular forces between the atoms.
Which trend decreases for metals down a group?
Melting Point
What trend in electronegativity do you see as you go down a group-family on the periodic table?
Electronegativity decrease down in a group.
